The medieval aqueduct of Salerno was built in the ninth century to supply water to the monastery of St. Benedict, at the eastern walls. It is located in the historic center of Salerno, under the hill Bonadies and its Arechi Castle.
It consists of two branches: one coming from the hills to the north, the other one from the high ground to the east of the city; both rejoined along the street Arce (which by their arches is named), at an edge of the old city walls. At first only stocked the Benedictine monastery, and later, a branch underground allowed to supply the convent of Piantanova, Via Mercanti.
The aqueduct was popularly renamed 'Bridges of the Devil' and it was said that it was built in a single night, with the help of demons, by the magician of the twelfth century Peter Barliario. The popular superstition considered also that venture under the arches between dusk and dawn would bring to the meeting with devils or evil spirits.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
